Do hydrangeas need topping for spring germination?

Hydrangeas must not be cut in spring, cutting once hurts once, and flowering is a problem.

The best time to prune hydrangeas is in autumn. In the spring, even though there are many dry leaves on the branches, if you look closely, you will notice that many small flower bones grow at the joints of each branch. These flower bones are difficult to spot, and if they are blindly cut off with scissors, it will be difficult to bloom again in the following time.

The correct way to do this is to just break off the dry branches on the top with your hands and clean the soil on the surface of the pot. Water and fertilize the soil in time, replenish water and nutrients, create a good living environment for it, and then wait quietly for it to bloom.

Trim attention. 2. If you leave it alone after the flowers, the tree will become weaker. Therefore, the flower stalk should be removed after flowering. The main point is to cut the upper part of the knot in the 2nd to 3rd knots from counting down from the flower.

3. If the branches that have grown into are cut off, the plant belongs to a kind of compensatory growth, of course, there is no nutrient accumulation, which will lead to less flowering, and spring pruning is easy to cut off the flower buds that have been differentiated in the previous year, which is the root cause of scarce flowering.

4. The old branches of hydrangeas do not need to be pruned.

No. Hydrangea topping is carried out in the peak growing season, specifically when the seedlings grow to 10 to 15 cm tall, they should be topped and treated to promote the lower axillary buds to better dream forehead hair. When the new shoots grow to 10 cm, the second time is carried out to promote a more concentrated nutrient concentration, so that the later stage can bloom better.

Note that topping must be carried out on sunny days, and should not be watered to avoid the wound from being wet and rotting.

Precautions for hydrangea planting.

The soil in which hydrangeas are grown is loose, fertile and well-drained sandy loam. However, the flower color is affected by the pH of the soil, and the acidic soil flowers are blue, and the alkaline soil flowers are red.

The potting soil for hydrangea planting should be kept moist, but the watering should not be too much, especially in the rainy season, attention should be paid to drainage to prevent root rot caused by waterlogging. In winter, indoor potted plants are preferably slightly drier. If it is too wet, the leaves are perishable.

Hydrangea is a short-day plant, and it is ideal to avoid the scorching sun when cultivating it, and 60% to 70% shade is ideal. Proper shade can prolong the flowering period when the sun is too strong in midsummer.

Does hydrangea need to be "topped"? On what basis is it judged whether to "top" or not?

Hydrangea seedlings need to be topped, because topping can make hydrangeas grow faster.

It is necessary to top, and after topping, the hydrangea seedlings will grow better, and the growth will be better.

Yes, although the size itself is relatively small, but a top can also ensure that the plant seedlings can grow better.

After the old hydrangea pile germinates, it generally takes about three months for the cover to bloom. Hydrangea old piles generally germinate in spring, and the northern region warms up late, generally germinating in March-April, and the flowering period of hydrangea is in June to August every year. If properly maintained, it can bloom normally, after the spring warms up, it needs to be placed in a good location for maintenance, sufficient light has a promoting effect on its growth.

The old hydrangea piles that are maintained will slowly sprout after the spring demolition and sleepy days gradually warm, and flower buds will grow from the top. If the temperature is right, the flower buds will fully bloom in about a month. But the higher the temperature, the faster it will turn on.

Try not to go above 30 or below 15. If the temperature difference is large and the low temperature is long, the flowers will bloom very late.

Hydrangea seedlings need to be topped, the leaf tips at the top of the plant can be cut off to promote its germination of side branches, when breeding hydrangea seedlings, it is necessary to apply compound fertilizer once a month in its growth season, and the hydrangea seedlings should be placed in a bright place to promote the differentiation of its flower buds, and after the hydrangea flowering, it is necessary to cut off the residual flowers that bloom and fail.

Hydrangea seedlings need to be topped, when topping hydrangea seedlings, it is necessary to prepare a sharp scissors that have been sterilized, cut off the leaf tips at the top of the plant, eliminate the top advantage of hydrangea seedlings, promote their germination of side branches, and spray carbendazim on the fracture of hydrangea seedlings to make them grow healthily.

Hydrangea seedlings need sufficient nutrients in the growth process, when breeding hydrangea seedlings, it is necessary to apply nitrogen, phosphorus and potassium compound fertilizer or well-rotted organic fertilizer once a month to accelerate its growth rate, and when fertilizing hydrangea, it is necessary to bury the fertilizer at the edge of the pot to avoid the plant being burned roots.

Hydrangea is a sun-loving plant, when breeding hydrangea seedlings, it needs to be placed in a bright environment, so that the plants receive no less than 6 hours of light per day, so that the growth rate of hydrangea seedlings is accelerated, but in the middle of summer, it is necessary to do shade measures for hydrangea seedlings to avoid sunburn.

When cultivating hydrangea seedlings, it is necessary to cut off the withered yellow leaves and diseased branches of the plant in time to avoid the loss of excess nutrients and promote its growth of new branches and leaves, and after the hydrangea flowering, it is necessary to cut off the residual flowers and flower stems of its failure to maintain the normal growth of the plant.

Hydrangea does not germinate for reasons.

Hydrangeas usually sprout in March each spring. If it does not sprout, it may be due to improper maintenance. Common causes are uncomfortable ambient temperatures, too much sunlight, and plants not germinating due to insufficient nutrients and moisture.

Hydrangea does not germinate treatment method.

Hydrangeas generally germinate after about 15 days of planting. If it does not germinate because the temperature is not suitable, it is necessary to control its ambient temperature. The temperature is best controlled between 18-28 degrees Celsius, which can promote germination.

In addition, if the sunlight is too strong, the hydrangea will not sprout, so it should be shaded or moved to a cool and ventilated place for maintenance. Of course, it is also necessary to ensure that its nutrients are sufficient, fertilize and water in time, and keep the potting soil moist.

Hydrangea maintenance after germination.

Light: Hydrangeas like shade rather than sun. After germination in spring, it is best to move to an outdoor semi-shaded place for maintenance.

When the sun is strong in summer, it should be properly shaded. In autumn, it should be maintained in a bright place. In winter, it needs to be kept indoors in a sunny place.

Water: Hydrangeas like moisture but are afraid of waterlogging, and should be watered frequently after germination, but not too much. Usually you should water more in spring and summer, less in autumn, and stop in winter.

Summary. I am Sister Rong, a rural elder sister who likes to raise flowers. In autumn, the hydroponic hydrangea germinates, you can pot the hydrangeas, when potting, as long as you use humus, peat, sand mixed soil, because the winter is cold, so it is not recommended to apply bottom fertilizer.

You can wait until the next year is vigorous and then fertilize it. After watering thoroughly, keep it in a shady place, and the temperature is above seven degrees in winter, under full sun. After the soil has dried, water it once in the middle of the day when the heat is high.

It will allow hydrangeas to overwinter smoothly.

It takes about a month for the old hydrangea pile to germinate to flower, and the temperature needs to be maintained between 15-30 degrees Celsius to provide a warm growth environment for the plant, which is conducive to the rapid flowering of the old hydrangea pile.

1. Flowering time

It takes about a month for the old hydrangea pile to germinate to flower, the higher the temperature, the faster the hydrangea old pile blooms, but the temperature can not be higher than 30 or lower than 15, if the temperature difference is too large, the low temperature time is too long, the old hydrangea pile will bloom very late.

2. Provide light

In order to let the hydrangea old pile quickly bloom with the spike flower, it needs to be placed on the open balcony with sufficient lighting, or moved to the outdoors, to ensure more than 4 hours of light time every day, but when the noon light is too strong, it should be shaded with a parasol to avoid the old hydrangea sprouts withering.

3. Comb the new shoots

After the old hydrangea pile grows new shoots, it is necessary to remove the thin, wilted and diseased buds like seedlings to save the nutrition of the plant and make other new shoots grow healthily, and then spray disinfection solvent on the cut surface to avoid the old hydrangea pile being infected with germs.

4. Supplement nutrients

In order to make the old hydrangea pile bloom quickly, it needs to be provided with sufficient nutrients, after the new shoots are pruned, you can apply fertilizer containing phosphorus and potassium to it, or add well-rotted organic fertilizer to provide more nutrients for flowering, so that the old hydrangea pile can grow quickly.

After the hydrangea is cut, it is more conducive to the emergence of new shoots in this way.

If you want hydrangeas to sprout, we should also prune more pairs of hydrangeas. When pruning, we must prune in place, keep the branches and leaves with full bud points, and cut off diseased branches, weak branches, and dead branches, so that hydrangeas can sprout a large number of new shoots in a hurry after pruning.

It should be a lack of nutrients in plants, and nitrogen and potassium fertilizers should be supplemented in time to promote the growth of plant rhizomes. Water regularly and place in a ventilated area.

Premature flowering of the bulb bottom bud can be treated with the following measures:

1.Strengthen management. Weeding in time, keeping the soil moist, and regular top dressing to make the plant grow in an orderly manner and avoid stunted buds at the bottom.

2.Hang the hydrangea upside down. In the spring, the upside-down hydrangea is used to hang the crown of the tree vertically to promote the germination of the bottom leaf buds and prevent the top buds from flowering too early.

4.Covered with shade. In the case of high temperatures and strong sunlight, it is possible to take the form of mulching and shading, which reduces the ambient temperature and reduces the dedormancy and premature flowering of the bottom buds.
